摘要：In this study, we argue that institutional factors determine the extent to which hospitals are symbolic or substantive adopters of information technology (IT) specific organizational practices. We then propose that symbolic and substantive adoption will moderate the effect that IT security investments have on reducing the incidence of data security breaches over time. Using data from three different sources, we create a matched panel of over 5,000 U. S. hospitals and 938 breaches over the 2005...

摘要：In this paper, we estimate the impact of enforcing the Convention on Cybercrime (COC) on deterring distributed denial of service (DDOS) attacks. Our data set comprises a sample of real, random spoof-source DDOS attacks recorded in 106 countries in 177 days in the period 2004-2008. We find that enforcing the COC decreases DDOS attacks by at least 11.8 percent, but a similar deterrence effect does not exist if the enforcing countries make a reservation on international cooperation. We also find ...

摘要：Many companies have adopted technology driven social learning platforms such as social customer relationship management (crowdsourcing customer support) to support knowledge sharing among customers. A number of these self-evolving, online customer support communities have reported the emergence of a coreperiphery knowledge sharing network structure. In this study, we investigate why such a structure emerges and its implications for knowledge sharing within the community. We propose a dynamic s...

摘要：Social media-based expert blogs are a crucial and credible online information source for consumers, yet little is known about the role of expert blogs for general consumer brand perceptions that bestow long-term value for the firm. On the basis of a novel dataset with 7,871 brand-day observations of over 131,000 expert blogs on major brands in the PC industry, this study reveals how expert blogs may act as a quality signal leading general consumers' perceptions of rival brands. Our analyses re...

摘要：Software development outsourcing (SDO) contracts are plagued with ex post opportunism and underinvestment problems. Property rights theory (PRT) argues that appropriate property rights allocation between vendors and clients can reduce opportunism and incentivize relation-specific investments. We conduct an in-depth content analysis of 171 real SDO contracts and empirically examine how project attributes and contract parties' bargaining power affect the allocation of intellectual property right...

摘要：Content generated on intra-organizational blogging platforms may help managers understand the emerging ideas, issues, and opportunities of their companies, whereas the difficulty is how to go beyond the overload of information and obtain an overall view. This paper proposes a system framework for extracting representative information from intra-organizational blogging platforms, as well as the REPSET (REPresentative SET) method, which serves as the core component of the extraction system. Draw...

摘要：The literature highlights the importance of product review information to a consumer, but limited knowledge exists on the provision of such information in a shopping website. This research uses information foraging theory (IFT) to determine how to provide product reviews. Product reviews differ according to whether the content is mainly on product attributes (i.e., attribute-oriented product reviews) or usage experience (i.e., usage-oriented product reviews). Two empirical studies were conduct...

摘要：This study documents variation across industries in creditors' perceptions of the risk of information technology (IT) investments. The associations we document between IT investments and both initial bond ratings and yield spreads suggest that credit-rating agencies and bond investors consider IT investments in automate and informate industries less risky than those in transform industries. We document that IT investments are associated with more volatile future cash flows in transform industr...

摘要：In this paper, we argue that the use of technology is structured not only by users, technology, and social context, but also by onlookers (i.e., actors for whom the use is visible, but who are not directly involved in the activities of use themselves). Building on the technology-in-practice lens and insights of an ethnographic study in operating rooms where nurses used mobile technology for various work-related and recreational purposes, we show how onlookers contribute to structuring collecti...
